Abstract
The utility model discloses a multi-layer cutter head of a diamond tool, which comprises three or more body layers, wherein the diamond solubility of each body layer is gradually reduced from two sides to the middle. The multi-layer cutter head of the diamond tool produces a recess or keeps flat all the time rather than produces a round notch during the cutting process, which achieves the effects of reducing the cutting area, increasing the cutting speed of the diamond tool and prolonging the service life.
Description
Technical field
The utility model relates to a kind of tool insert, more particularly, is a kind of diamond tool cutter head of layering.
Background technology
What the whole cutter tooth of existing diamond tool cutter head adopted is with a kind of carcass with a kind of diamond concentration, and the material of whole cutter tooth is with a kind of.This just causes the diamond tool cutter head in the cutting operation process, and cutter head is worn down to round mouth easily, thereby makes diamond tool cutting area increase, and not only influences the diamond tool cutting speed but also can reduce service life of diamond tool.
Summary of the invention
Because the problems referred to above that prior art exists, the utility model proposes a kind of layering diamond tool cutter head, and it can effectively address the above problem.
To achieve these goals, the utility model has adopted following technical scheme:
The utility model proposes a kind of layering diamond tool cutter head, comprises body piles more than 3 layers or three layers, and the diamond solubility of said body piles from both sides to the centre weakens gradually.
Owing to adopt above technical scheme; The layering diamond tool cutter head of the utility model can not form round mouth in the process of cutting; But form matrix or remain the plane, reduce the cutting area thereby reach, improve the diamond tool cutting speed and the effect in service life.
Description of drawings
Fig. 1 is the sketch map of an embodiment of the utility model.
Among the figure: 1, the upper strata body piles; 2, the intermediate layer body piles; 3, lower floor's body piles.
The specific embodiment
According to accompanying drawing and specific embodiment the utility model is described further below:
A kind of layering diamond tool cutter head comprises body piles more than 3 layers or three layers, and the diamond solubility of body piles from both sides to the centre weakens gradually, and hardness also weakens thereupon.
As shown in Figure 1, be the sketch map of an embodiment of the utility model.Be that the wide 4mm specification of the high 9mm of 18mm is an example with a length among the figure; Each cutter head is made up of 3 layers of carcass: body piles 1 specification in upper strata is: the wide 1.3mm of the high 9mm of long 18mm; Middle body piles 2 specifications are: the wide 1.4mm of the high 9mm of long 18mm, lower floor's body piles 3 specifications are: the wide 1.3mm of the high 9mm of long 18mm.The prescription of upper strata body piles 1 is: WC (tungsten carbide): 5%, and Co:38%, Ni:8%, Cu:36%, Sn:3%, Cr:2%, Fe-P:8%, diamond solubility: 48%; The prescription of middle body piles 2: Co:38%, Ni:8%, Cu:41%, Sn:3%, Fe-P:10%, diamond solubility: 30%; The prescription of lower floor's body piles 3: WC:5%, Co:38%, Ni:8%, Cu:36%, Sn:3%, Cr:2%, Fe-P:8%, diamond solubility: 48%.Because the difference of prescription; The hardness of following three layers of carcass differs widely in making upward; Diamond solubility difference wherein the levels carcass relative intermediate layer body piles 2 more firmly, more wear-resisting, make body piles 2 wearing and tearing earlier in the middle of diamond tool is in the process of cutting thereby diamond solubility is higher.
Being made as of this layering diamond tool cutter head: carcass powder behind three-dimensional blender machine batch mixing with cold press each layer cold-press moulding of each cutter head; Wrap up upper strata, intermediate layer and lower floor with graphite jig; Reusable heat presses sintering machine to carry out sintering; The sintering maximum temperature is 820 °, and maximum pressure is 180Kn, heat-insulation pressure keeping 3 minutes.The vestige that tangible multilayer combination is arranged through the cutter head of hot forming.
But the above-mentioned specific embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
Claims (1)
1. a layering diamond tool cutter head is characterized in that: comprise body piles more than three layers or three layers, and the diamond solubility of said body piles from both sides to the centre weakens gradually.
